2.1.3. Lab – Virtual Server Packet Processing¶
2.1.3.1. Task 1 – Create additional Virtual Servers¶
Create a wildcard virtual server and pool, test and observe various traffic under different configurations to determine how virtual servers process new inbound connections. You will be using tcpdump from window1, virtual server statistics, as well as a browser to determine behavior.
Create wildcard_vs 10.1.10.100:* with TCP profile, Automap and wildcard_pool of 10.1.20.11:*
- To create the wildcard pool, go to Local Traffic > Pools > Pool List and select Create.
Name wildcard_pool Address 10.1.20.11 Port * Don’t forget to Add the pool member to the New Members box before you hit Finished.
To create the wildcard virtual server, go to Local Traffic > Virtual Server and select Create.
Name wildcard_vs Destination 10.1.10.100 Service Port * Source Address Translation Automap Default Pool* wildcard_pool Don’t forget to hit Finished.
Note
You didn’t enter the source addresses allowed. Go to your new virtual server and look at the Source to see the default source addresses allowed.
2.1.3.2. Task – Testing Virtual Server Packet Processing Behavior¶
Many of your virtual servers have the same virtual address. You will now test various behaviors.
Clear virtual server stats.
Observe connection statistics (VS stats) for each of the following
- Browse to http://10.1.10.100:8080
Attention
Q1. Which VS is used for web traffic over port 8080?
- FTP to 10.1.10.100
Attention
Q2. Which VS is used for FTP traffic?
- Browse to http://10.1.10.100
Attention
Q3. Which VS is used for this web traffic the default HTTP port? What port was used?
Clear virtual server stats.
Modify the wildcard_vs to only allow connections from a Source of 10.1.10.0/24
Browse to http://10.1.10.100
- Observe connection statistics (VS stats)
Attention
Q4. Which VS is used for web traffic?
Clear virtual server stats.
Modify wildcard_vs to include the default Source of 0.0.0.0/0.
